automated 3D printed cardboard

First of all thank you for the great music ressource I could find here.
I bought a 30 note music and wanted to automated the punching process.
I ended coding some script to automatically generate from a midi file a 3D printable set of boards.


Should one of you be interestested, here is a link to thingiverse where I posted the application too (thing:5390853) : www.thingiverse.com/thing:5390853
